前言

本文教程主要针对 Hexo 博客,对博客的文章发布时间、文章分类、文章标签的维度绘制统计图,使用的是 ECharts 开源可视化库。具体效果可以点击本站的 统计--文章统计 页面查看。

  • 2021-05-17 新增主题“明暗模式”下统计图的颜色切换。
  • 2021-11-30 新增标签统计图和分类统计图的页面跳转功能。
  • 2022-05-07 新增文章发布统计图自定义统计开始日期属性 data-start
  • 2022-08-15 V2.0 适配多层级分类,单层分类时显示饼状图,多层分类时显示旭日图; 多分类时页面也可以跳转到子分类页面。

如果想绘制博客站点访问统计图的可以参考文章 Hexo 博客实时访问统计图

新建 charts 页面

hexo new page charts

[Blogroot]\source\ 目录下新建 charts 文件夹,并在新建的 charts 文件夹下新建 index.md 文件,添加以下内容:

引入 ECharts.js

echarts.js 必须在渲染 echarts 实例的 JavaScript 前引入。

以 butterfly 主题为例,可以在 [Blogroot]\_config.butterfly.ymlinject 配置项中引入 echart.js 文件。

更多统计图的自定义属性可以查看 ECharts 配置项文档,根据自行喜好对 ECharts 统计图进行修改。

使用统计图

在上文新建的 [Blogroot]\source\charts\index.md 文件中添加以下内容:

1
2
3
4
5
6
<!-- 文章发布时间统计图 -->
<div id="posts-chart" data-start="2021-01" style="border-radius: 8px; height: 300px; padding: 10px;"></div>
<!-- 文章标签统计图 -->
<div id="tags-chart" data-length="10" style="border-radius: 8px; height: 300px; padding: 10px;"></div>
<!-- 文章分类统计图 -->
<div id="categories-chart" style="border-radius: 8px; height: 300px; padding: 10px;"></div>

<!-- 文章发布时间统计图 -->
<div id="posts-chart" data-start="2021-01" style="border-radius: 8px; height: 300px; padding: 10px;"></div>
<!-- 文章标签统计图 -->
<div id="tags-chart" data-length="10" style="border-radius: 8px; height: 300px; padding: 10px;"></div>
<!-- 文章分类统计图 -->
<div id="categories-chart" data-parent="true" style="border-radius: 8px; height: 300px; padding: 10px;"></div>

当然也可以在其他页面引入文章统计图,如果出现图表显示不全的现象可以修改 divheight 属性。。

  • posts-chartdata-start="2021-01" 属性表示文章发布时间统计图仅显示 2021-01 及以后的文章数据。
  • tags-chartdata-length="10" 属性表示仅显示排名前 10 的标签。
  • categories-chartdata-parent="true" 属性表示 有子分类 时以旭日图显示分类,其他 无子分类设置为false不设置该属性设置为其他非true属性 情况都以饼状图显示分类。

具体效果如下图所示:

多层分类旭日图 分类饼状图

适配明暗模式

统计图内部文字的颜色通过 charts.js 文件中的 var color = '#000' 设置,如果需要适配博客明暗模式更改统计图文字颜色,以 butterfly 主题为例,可以修改三处的 color:

1
2
- var color = '#000'
+ var color = document.documentElement.getAttribute('data-theme') === 'light' ? '#4c4948' : 'rgba(255,255,255,0.7)'

同时引入自定义 js 文件并添加以下代码:

注:上面的章节已经包含此段代码,此章节只用于旧版本的更新,新部署的用户可以忽略此章节。

为 ECharts 标签统计图和分类统计图增加点击跳转的功能,分别在 postsCharttagsChartcategoriesChart 内部增加以下 js 即可实现页面跳转。

// 标签页面跳转

Hexo 三连

执行 Hexo 三连

1
hexo clean && hexo g && hexo s

可能遇到的问题

  • 控制台报错 Uncaught ReferenceError: require is not defined

    解决方案:

    不能直接在页面引用 charts.js,是放在主题文件夹 [Blogroot]\themes\butterfly\scripts\helpers\ 里面,hexo g 的时候会在 div 后面追加 echarts 图的 js。页面不需要引入 charts.js

  • 控制台报错 Uncaught ReferenceError: echarts is not defined

    解决方案:

    需要在统计图的前引入 echarts.js 文件,最好是在页面的头部引入。

  • 控制台报错 Cannot find module 'cheerio'

    解决方案:

    安装 cheerio,控制台执行 npm i cheerio --save
